Nice weather where?

With so much weather data available it would be possible to filter for "Nice Weather".
It could be an unique application no weather internet sites or weather providers have this at the moment.
Windy could be the first. So, the question is, where is it nice agreable weather. about 23 degreees celcius, light wind, low humidity and sunshine. Of course some like it hot or cold with no wind and sunshine. But the first step is, about 23 degrees, light wind and sunshine.
Who can make this app?
